Hello I made some server and it works fine, but when I use Mo creatures on the server and I go on the server it crashes:

Mhmhmhm.

First, does your server have the same mods as your client does?Secondly, it looks like the game is crashing due to an entity spawning that has a packet of 187. I have no idea if that equates to an ID or not, but if it does, it most likely is the MoCreatures "pussycat", unless if that ID was pushed out of the way, or if im wrong, then hehehehFinally, can you connect to the servers you make in the first place?
